It takes a Panaflo fan swap to bring the SS to the same low noise level as the Nexus. This is much less than $30. But the Nexus fan has the capacity to ramp up to ~38 cfm at full power (should you ever push it that hard), which means it should always run cooler, while the Panaflo can do only 24 cfm max. My Panaflo modded Seasonics do run hotter than the stock Nexus and there is little appreciable noise difference between the two.

my way of looking at it is this: the nexus absolutely rocks. im using a couple right now and they're extremely quiet. $30 is a drop in the bucket that you wont really miss later on, but you'll have a totally sweet power supply.

I have an idea, but it might not work. How about using an M1A or H1A instead of an L1A on the Seasonic. That way you could get the higher airflow, but still have the quiet technology that the panaflo offers.

This might not work if: 1) the M1a or H1a has poor bearings compared to the L1a (not likely right?), or 2) the themal control circuitry in the Seasonic is not as advanced as the Nexus (this seems to be true)

Thanks for all the advice! I'm definitely not up for swapping fans out of a power supply, and price isn't a *huge* issue, so I'll most likely end up with a Nexus. Might have to wait until my tax returns show up, though.

For swapping the fan in the Seasonic with an L1A. What is the wiring requirement for that. Can you still use the thermistor? I can't quite tell from the pics if the thermistor is part of the fan or part of the PSU.

I guess what I am saying, is there a fan connector inside the Seasonic PSU or what?

I am considering getting the Seasonic, cutting the grill out and replacing it with a wire one, and replacing with an L1A

Well, I have an M1A - 1BX (though haven't been able to get the RPM monitoring to work correctly, it bounces from the correct speed to zero )

At 12v the M1a is definitely audible, but at less than about 8-9v it becomes fairly silent. I'll be putting it in a True380 as soon as the 92mm L1A comes in. I'll be mounting it with the EAR fan mounts. As soon as I have it up and running, I'll give a report, should be monday or so.
